使用IOlecommandTarget::QueryStatus在IE中获取打印取消通知
原标题:Getting print cancelled notification in IE using IOlecommandTarget::QueryStatus

如果用户在IE中的打印提示中选择了取消按钮,是否可以收到通知?基本上我想要一个取消打印的通知。

我在某个地方读到,IOlecommandtarget接口可以用于通知我们自己的控件,但也可以用于打印等系统控件吗?有人能帮忙吗?

问题回答

如果使用IOleCommandTarget::Exec方法,则取消时将获得OLCMDERR_E_CANCELD作为返回值。
